油层孔隙压力解释与自动扫描技术

油层孔隙压力自动扫描是利用数字测井数据进行油层孔隙压力解释的一项新技术，该项技术研究从自然电位测井原理出发，分析自然电位的构成因素，利用过滤电位与压差的相关性建立压力解释数学模型，应用ＲＦＴ实测数据确定参数系列。采用计算机自动将所需各曲线的数据按对应深度读度读值后赋给数学模型，并附加必要的边界条件，进行逐点计算，形成孔隙压力剖面线，通过自动扫描软件即可实现测井现场孔隙压力剖面的计算和打印。也可在室

Interpretation of Reservoir Pore Pressure and Its Automatic Scanning Technique

Automatic pore pressure scanning is a new technology for pressure analysis by digital logging data. Based on the logging principle of self-potentical the mathematical model for pressure analysis is established, which makes use of the correlativity between filtering potential and differential pressure and a series of parameters extracted from RFT pressure test result. Using the mathematical model the automatic scanning soflware is made and loaded in the Digital Logging system, with which the pore pressure profile can be printed out on site. It is precise, fast, cost-efficient and easy to use.
